Current Projects: A Ku-Ka Band Single Channel Beamforming Receiver

The research objective of this paper is to investigate high performance MMICs for ultra wideband, highly linear beamformer chipsets for phased array communication systems from Ku to Ka bands, which cover the operating frequency ranges of satellite communications, and terrestrial microwave communications. Based on scaled silicon-based technologies, key sub-blocks, including wideband low noise amplifiers, wideband variable gain amplifiers with reduced phase error, and an active phase shifter has been implemented.
